Coal inactivation processing apparatus

摘要

The purpose is to produce inactivated coal in a short time while preventing spontaneous combustion. A coal inactivation processing apparatus for inactivating coal with an oxygen-containing process gas, wherein the coal inactivation processing apparatus comprises a kiln assembly (103) for passing coal (4) from the base-end side to the distal-end side therein, base-end-side process gas supply means (121-125) for supplying a process gas (13) to the base-end side of the interior of the kiln assembly (103), distal-end-side process gas supply means (131-135) for supplying a process gas (14) to the distal-end side of the interior of the kiln assembly (103), process gas oxygen concentration adjusting means (124a, 134a, 135, 136a) for adjusting the oxygen concentration of the process gases (13, 14) supplied into the kiln assembly (103), and a cooling device (160) for cooling the coal (4) inside the kiln assembly (103).
